Abstract
An assembly for aligning and supporting an adapter flange for connecting fluid pressures to a pressure sensor body in place on the body and to keep the flange in an unsealed condition to prevent pressurizing the body and flange until installation of permanent fasteners. The support fasteners keep the flange oriented in its normal usable position, but the fasteners retain the flange spaced from the body sufficiently so that the flange will not seal. This will prevent accidentally pressurizing the flange and pressure sensor body until permanent fasteners have been installed. The pressure sensor body is provided with threaded openings for receiving permanent fasteners and the body and flange are shipped with at least one extra set of permanent fasteners different in length from the fasteners used on the flange to permit adding adapters for a process correction. The threaded openings in the body are counter bored an amount selected so that when a different thickness adapted is used for process correction, only the correct length fasteners will be capable of being threaded into the body bores.
